In order to ensure that the order of the result sets within the returned T:System.Data.DataTableReader, if a T:System.Data.DataTable within the T:System.Data.DataSet is empty, it is represented by an empty result set within the returned DataTableReader. Because this overloaded version allows you to supply a list of DataTable instances as parameters, you can specify the order in which the result sets appear within the returned DataTableReader.

This example, a Console application, creates three T:System.Data.DataTable instances and adds each to a T:System.Data.DataSet. The example calls the M:System.Data.DataSet.CreateDataReader(System.Data.DataTable[]) method and displays the contents of the returned T:System.Data.DataTableReader. Note that the order of the result sets in the DataTableReader is controlled by the order of the DataTable instances passed as parameters. The example displays the results in the Console window.
